Description
When your gas or packaged HVAC system begins locking out due to lack of flame detection, the Carrier 48GS400192 flame sensor steps in as the critical safety component you need. This genuine OEM sensor from Carrier ensures reliable flame monitoring, restoring safe ignition with minimal downtime and ensuring your system operates as designed.
Key Features
- Factory Authorized OEM Part: The 48GS400192 is a factory designated part, meaning it meets Carrier’s original specifications for fit, performance and durability.
- Essential Safety Function: It senses the presence of flame in the burner assembly and signals the control board via the ionization circuit — preventing gas flow if flame is not detected, thus safeguarding the unit.
- Compact, Durable Design: Lightweight and built for the harsh environment of a furnace burner compartment — many listings show a weight of only ~0.07 lbs.
- Easy Replacement: Designed for direct drop in replacement in compatible Carrier, Bryant and Payne units that specify this part number — greatly simplifying service calls.
- Improves System Reliability: A worn or faulty flame sensor often causes repeated lock outs or pilot problems; replacing it helps restore stable ignition and prevents inconvenient shutdowns.
